But it is not a default. Most software distributions package postfix configured to run in a chroot. That makes it possible for the chroot'd postfix to have a different /etc/resolv.conf configuration than the rest of the system. It is possible to set up postfix to use a local caching resolving that has no restrictions while the rest of the system uses one of the public resolvers. But it would be a local customization needed to do it. The distro package init scripts copy resolv.conf into the chroot. Prevent that and apply your own setting. Bob
